    GL extensions and nVidia

    Hi,

    I don't understand why my card (GeForce2 Pro) does not support WGL_EXT_extension_string or WGL_ARB_extension_string. In nVidia ext. specifications I found that it is supported with NV1x and later chipsets. Also I found that NV_vertex_buffer_object is supported with detonators R40. I haven't got VBO. I've got detonators 43.45, so what's going on?

    Thanks in advance

    Try to f**k this ext string & call getprocaddr for everything you need, if pointers are nulls, sorry, if not, they just forgot to type exts in string

    Thanks! It worked. I got upset with it, what the heck is glGetString(GL_EXTENSIONS) for?

    it's kinda tells what extensions are available with your implementation but offen misses occurr like this one.Everything is documented thought so not to worry!
    The pain is coming...THIS SUMMER!

    i've got geforece 2 ti and updated the driver to the 4.4.0.3ӣWell the opengl extension does include Vertex_object_buffer .
    Another thing you might do is to download the lesson24 application from NeHe. Lesson 24 can check out how many extension your Graphic card support.

    From the OpenGL specs:

    "Applications should call wglGetProcAddress to see whether or not wglGetExtensionsStringARB is supported."

    The nVidia drivers are doing the right thing.

    OK, Looks like that I will have to get detonators 44.03. But with my modem connection it'll be too expensive (18.8 MB file).

    Thanks
